To @ZZ whom' it may con/cern,-

A Be it known that I,WILI.IAM M. STEvENsoN, a citizen of the United States, and a resident of Springfield, Massachusetts, have invented certain Improvements'in Woven Fabrics, of,

which the following is a specification.

My invention consists of a woven fabric 4especially designed for carpeting and ycontaining weftthreads composed of strands or 1o fibers of wool, cotton, or like material spun into yarn and other weft-threads consisting of twisted strips of paper, the object of my invention being to provide a fabric which will .i possess desirable qualities of both a wool or I5 cotton fabric anda paper fabric yandwill also possess certain advantages over either of these fabrics.

In the accompanying drawings, Figure 1 is a face view of a piece of fabric made in aczo cordance with my invention. Fig. 2 is an exaggerated section of the same, taken on the line t a, Fig. 1, or in the direction of the weft. Fig. 3 is an exaggerated section of the fabric,

taken on the line b 6,'Fig. 1, or .in the direc- 2 5 tion of the warp; and Fig. A is a view similar to Fig. 3, but illustrating another form of fabric embodying my invention.

rIhe fabric shown comprises binding warp' threads 1 and 2 'and heavier separator warpthreads 3, these threadsI being interwoven with two sets of weft-threads 4 and 5, the weftthreads i beingc'omposed of strands or fibers of wool, cotton,'or like material spun-into,

shown in the drawings simply act as separator# threads, the warp-threads 1 and 2 binding, first,

l a l.weft-thread of one face and then a weftthread of the other face, and the warp-threads 1 binding one face when the warp-threads 2 are bindingthe other face, as shown in Fig. 3,

sea11i0.69,270. (specimens.)

I so as to tie the two faces of the fabric firmly together and form a strong, well-tied, and homogeneous fabric.

The use of the paper weft-threads in connection with the wool or cotton weft-threads not only cheapens the fabric ascompared with one using weft-threads composed entirely of wool, cotton, or the like, but it has the fur- 4 ther important effect off stiffening the fabric and giving it afirmer body than one composed entirely of wool, cotton, or like material, the stiff paper weft-threads rendering it unnecessary to bind the fabric at the usual close intervals, so that the fabric can bey woven with half the quantity of binding warp-threads which would be required if the fabric was wholly of wool, cotton, or the like. The carpet, moreover, possesses the advantage over one made wholly or largely of paper that it is warm enough for use during the winter season, and, if desired, the carpet may -be made with all of the paper weft-threadson oneI face and allvof the wool or cotton weft-threads on the other face, as shown, for instance, in Fig. 4E, the wool face being used uppermost during the winter season and the paper face being uppermost duringk the summer season, thus combining in one fabric the advantages of lboth forms of carpet. f

Although I prefer to use separator warpthreads 3 of a heavier character than the binding warp threads, so as to act as stufi'erthreads and give body to the fabric, this is not absolutely essential to the proper carrying out of my invention, as the warp-threads 3 would serve their function as separators whether coarse or fine.

Having thus described my invention, I claim and desire to secure by'Letters Patent- 1.' A woven fabric having binding warpthreads combined with weft-threads disposed in two planes, some of the weft-threads being composed of wool, cotton, or the like, and the other weft-threads being composed of twisted strips of paper, thereby giving a firm body to the'fabric and dispensing with the necessity of closely grouping'the the warp-threads, substantially as specified.

2. A woven fabric having binding warpthreads combined with weft-threads disposed in two planes with separator warp-threads between them, some of the weft-threads being composed of wool, cotton, or the like, and the other weft-threads being composed of twisted strips of paper, thereby giving a firm body to the fabric and dispensing with the necessity of closely grouping the warp-threads, substantially as specified.

3. A woven fabric having binding Warpthreads combined with weft-threads disposed in two planes, having between them separator warp-threads heavier than the binding warpthreads', some of the weft-threads being composed of wool, cotton, or the like, and the other weft-threads being composed of twisted strips of paper, thereby giving arm body to the fabric and dispensing with the necessity of closely grouping the warp-threads, substantially as specified.

4. A woven fabric having binding warpthreads combined with weft-threads disposed in two planes, the weft-threads of one plane being'composed'of wool, cotton, or the like, and the weft-threadsof the other plane being composed of twisted strips of paper, substantially as specified.

5. A woven fabric having binding warpthreads combined with weft-threads disposed in two planes with separator warp-threads between them, the weft-threads of one plane being composed of wool, cotton, or the like, and the weft-threads of the other plane being composed oftwisted strips of papel', substantially as specilied.

6. A woven fabric having binding warpthreads combined with weft-threads disposed in two planes having between them separator warp-threads heavier than the binding warpthreads, the weft-threads of one plane being composed of wool, cotton, or the like, and the weft-threads of the other plane being composed of twisted strips of paper, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
